Steve,
Let me start by saying that I like the M6. I actually prefer the Classic rod/box set-up and trigger toggle location to the MXT or XLT or DFX.
I prefer some of the functions of the MXT, however, and about the only think I DON'T like about the MXT is the noisy threshold audio.
Well, I guess I like the gain control/circuitry of the M6, too, over the MXT. But, like you, I also like it compared with the DFX and I think it will sell well against the DFX & XLT in most markets, for sure!
I am not adding one to my battery yet, and most likely won't. I'll wait-and-see what the future holds for a more versatile and quiet operating new model that might be a little more 'up-line.'
I do wish the tones were laid out differently, but I also realize that, due to the operating frequency, that might be some of the best they can do. Where I think they missed the boat is by not bringing out a unit to compete with the growing number of multi-notch models.
So, while the M6 is a good unit, there is a lot of reason for a more avaid hunter or one with more areas of interest, to consider the MXT for the piddly little $100 difference.
So, while they came close in several ways, I think I wiull stick with my X-you know what for now. Besidess, with the excellent 18-segment notch system, 4 tone audio, and the gold jewlery performance with the new 18.75 kHz coil, it's now going to be my primary gold jewlery hunting unit (location will be the key element in selecting where I use that coil).
Hope you're Matrix M6 sales this year will prove our belief in the appeal of it to the DFX, and all the best to you.
